The version is 1.3.2, fvar4dat, time-activity data analysis made easy. fvar4dat can add Gaussian noise to time-activity data: SD(t) = Sqrt( c * TAC(t) * Exp(lambda*t) / frame_length ) TAC_noisy(t) = TAC(t) + SD(t)*G(0,1) Input and output TAcs are assumed to be decay corrected. If the output filename extension is *.sd or *.cv,...
